It is actually quite easy to boot Windows virtualized using KVM. But to properly use the UEFI bootloader, suitable QEMU arguments are required. Here is a lightly commented QEMU command I use to boot virtual Windows 10 I have on a separate partition.

Our ISP (internet service provider) finally started offering IPv6. On the server, I received static configuration. Here, they are using DHCP6 with prefix delegation and it isn’t as straightforward as one would expect.

RaspberryPi is a nice, small device which can be used for various automation purposes, internet of things or as an advanced camera. I have been using 5 RPis as a camera with motion detection and post-processing. This application requires high reliability and it was a pretty long journey until all the issues were solved. Here I am writing the most important things I have learned so you don’t need to go through the same stuff again (my cameras were placed on a remote location, making the whole process more complicated).

Nginx is a great, fast HTTP server but I often stumbled upon some problems when configuring it. Mainly because the fact that official documentation is not concrete and clear enough.

That’s why I decided to write down some notes and experience I gained during nginx usage. Some of comments mentioned here may become obsolete or may not be true completely, but this is what I used and what worked for me.
